An evacuated cylinder has a volume of 50 liters. If 20 liters of nitrogen gas and 20 liters of oxygen gas are pumped into this evacuated cylinder, how much of the cylinder is filled with the two gases?

a. Only 80 percent because only 40 out of 50 liters are used.
b. The entire container because gases will expand to fill it.
c. Only 80 percent because of the low molecular weight of the two gases.
d. The entire container because of the low molecular weight of the two gases.

Option b. The entire container because gases will expand to fill it.

Explanation:

One exceptional ability of gas is to fill the container in which they are poured into. Since the forces of cohesion within the gas molecules are negligible, the gases will expand to fill the entire container

Sodium, group one, because in total the electron configuration shows 11 electrons and the only element with 11 electrons is sodium, a chemical property of sodium is it reacts quickly with water to produce sodium hydroxide and hydrogen.
